Description

display device {DISPLAY APPARATUS}

The present application relates to a display device for emitting an image.

In recent years, as society enters a full-fledged informatization realm, the field of display that processes and displays a large amount of information has developed rapidly, and various various flat panel display devices have been developed and are in the spotlight in response to this.

Since the flat panel display uses a glass substrate to withstand high heat generated during the manufacturing process, there is a limit to light weight, thinness and flexibility. Therefore, a flexible display device manufactured to maintain display performance even when bent like paper by using a flexible material such as plastic instead of a conventional inflexible glass substrate is rapidly emerging as a next-generation flat panel display device.

On the other hand, recently, research for realizing the front part from which the image is emitted as a full screen display is being actively conducted. A full screen display is an image in which the front part is realized as a full screen without a hole by placing ancillary devices such as a camera, an illuminance sensor, and a proximity sensor arranged to protrude from the front part inside the main body (or the lower part of the display). means the device.

Since the full-screen display can arrange ancillary devices inside the main body (or the lower part of the display), there is no configuration that protrudes out of the display, so it can give satisfaction to the user in terms of design, and the display placed on the front Since there is no need to provide a hole, there is an advantage that the manufacturing process can be simplified.

However, since the full-screen display is an accessory device, for example, because the camera is disposed inside the body (or the lower part of the display), the external light incident toward the camera is reflected from the surface and the inside of the camera to the inside of the body (or the lower part of the display) By being re-reflected on metal materials such as electrodes and wiring placed on the camera, the external light directly incident on the camera from the outside and external light re-reflected from the inside of the body (or the lower part of the display) reach the camera, resulting in image overlap or noise. There is a problem that arises.

An object of the present application is to provide a display device capable of preventing image overlap or noise generation due to reflection of external light in the interior of the main body (or the lower part of the display).

A display device according to an embodiment of the present application includes a display panel having a first area and a second area, a main body supporting the display panel, an auxiliary member disposed inside the main body and overlapping the first area of the display panel, and a display panel It may be provided to include a light absorption unit disposed in the second area of the display panel to surround the first area of the display panel.

In the display device according to the present application, the light absorbing part disposed in the second area of the display panel is provided to surround the first area of the display panel, thereby preventing external light reflected from the auxiliary member from being re-reflected to the auxiliary member, thereby preventing image overlap or Noise can be avoided.

1 to 4 , the display device 1 according to an example of the present application includes a display panel 2 , a body 3 , an auxiliary member 4 , and a light absorption unit 5 . The display panel 2 includes a first area A1 and a second area A2 . The auxiliary member 4 may be disposed inside the main body 3 (or under the display panel 2 ). The light absorbing part 5 may be disposed in the second area A2 of the display panel 2 to surround the first area A1 of the display panel 2 .

The first area A1 according to an example may be provided as a transparent area, and the second area A2 according to an example may be provided as an opaque area. An auxiliary member 4 such as a camera, an illuminance sensor, and a proximity sensor is disposed under the first area A1 so that external light (EL, shown in FIG. 2A ) can reach the auxiliary member 4 . It may be provided as a transparent area. On the other hand, since the auxiliary member 4 is not disposed in the second area A2, it may be provided as an opaque area.

In both the first area A1 and the second area A2 , image light may be emitted toward a user positioned outside the display panel 2 . More specifically, the first image light L1 (shown in FIG. 2A ) emitted from the first area A1 and the second image light L2 emitted from the second area A2 (shown in FIG. 2A ) ) may be emitted toward the user.

In the present specification, description will be made based on the fact that a user (not shown) is positioned outside the display panel 2 in the Z-axis direction (shown in FIG. 2A ). The Z-axis direction may mean a thickness direction of the display device 1 according to an example of the present application. The X-axis direction (shown in FIG. 1 ) is a direction perpendicular to the Z-axis direction, and may mean a horizontal length (or width) of the display device 1 according to an example of the present application. The Y-axis direction (shown in FIG. 1 ) is a direction perpendicular to each of the Z-axis direction and the X-axis direction, and may mean a longitudinal length of the display device 1 according to an example of the present application.

The display panel 2 may be a display device emitting image light. The image light may be a sum of the first image light L1 and the second image light L2. The display panel 2 may be a flexible display panel manufactured by using a flexible material such as plastic to maintain display performance even when bent like paper. The display panel 2 according to an example may have an overall rectangular plate shape, but may also have other shapes.

The first area A1 of the display panel 2 is a partial area of the display panel 2 disposed at a position corresponding to the auxiliary member 4 , and may be provided transparently because it emits light from both sides. Accordingly, the light emitted from the first area A1 of the display panel 2 may be emitted to the outside and the inside of the main body 3 . In addition, the external light EL may be incident to the auxiliary member 4 through the first area A1 .

The second area A2 of the display panel 2 is an area excluding the first area A1 of the display panel 2 and may be provided opaque because it emits light on one side. For example, the second area A2 of the display panel 2 is provided in a top emission method, so that the emitted second image light L2 may be emitted toward the user.

1 and 2A , the first area A1 of the display panel 2 may have a smaller size than the second area A2 . This is because the size of the auxiliary member 4 is smaller than that of the main body 3 .

Meanwhile, the first area A1 may be disposed at a position spaced apart from the edge of the display panel 2 . In this case, as shown in FIG. 2A , second areas A2 may be disposed on both sides of the first area A1 . Although not shown, the first area A1 may be disposed at an edge of the display panel 2 . In this case, the auxiliary member 4 may also be disposed below the edge of the display panel 2 .

The first area A1 and the second area A2 of the display panel 2 may be areas not covered by the main body 3 . Accordingly, the user can view the image output from the display panel 2 through the first area A1 and the second area A2 of the display panel 2 . In FIG. 1 , a part of the body 3 may be disposed in a bezel area.

Since the second area A2 is single-sided light emission (or top light emission), all of the emitted second image light L2 may be emitted toward the user, but since the first area A1 is double-sided light emission, the first image light A portion of L1 may be emitted toward the user, and the remainder of the first image light L1 may be emitted toward the light absorption unit 5 . Accordingly, the luminance of the first image light L1 may be lower than the luminance of the second image light L2 .

However, in a general display device, an auxiliary member such as a camera is not disposed inside the display panel but protrudes to the outside, so that an image is output while being superimposed on the auxiliary member like the first area A1 of the display device 1 of the present application. It is provided so that the image is not output even if there is no configuration or there is an overlapping area on the auxiliary member. Accordingly, in the display device 1 according to an example of the present application, although the luminance of the first image light L1 is lower than the luminance of the second image light L2, the display device 1 shows an image even in the first area A1 compared to a general display device. Since light is emitted, it may be provided so that the user does not have a sense of difference between the images output from the first area A1 and the second area A2 .

Accordingly, in the second pixel P2, components disposed under the organic light emitting layer P24 may be formed of a reflective material or may be opaque so that all light emitted from the organic light emitting layer P24 may be emitted toward the user. . For example, the first electrode P22 of the second pixel P2 may be provided as a reflective electrode, and may include a substrate P21, a circuit element layer PCL, an insulating layer IL, a second bank P23, and the second thin film transistor P27 may be opaque.

However, the components disposed above the organic light emitting layer P24, for example, the second electrode P25 and the encapsulation layer P26 of the second pixel P2 transmit light emitted from the organic light emitting layer P24 and emitted upward. In order to improve , the second electrode P15 and the encapsulation layer P16 of the first pixel P1 may be transparently provided.

Like the first organic emission layer P14a, the second organic emission layer P14b, and the third organic emission layer P14c, it may be provided to emit red light, green light, and blue light.

In the display device 1 according to an example of the present application, since the first area A1 is transparent and the second area A2 is opaque, the components disposed in the first area A1 and There may be differences in processes between the components disposed in the second area A2 .

For example, the substrate P11 disposed in the first area A1 should be transparent and the substrate P21 disposed in the second area A2 should be opaque. After being completely disposed in the area A2, an opaque material is further formed only on the substrate disposed in the second area A2 so that the substrate P11 disposed in the first area A1 is transparent and the second area ( The substrate P21 disposed on A2) may be opaque.

As another example, the transparent substrate P11 may be formed by depositing a transparent material in the first area A1 , and the opaque substrate P21 may be formed by depositing an opaque material in the second area A2 .

Similar to the above process method, the first electrode P12 and the bank P13 disposed in the first area A1 are transparent, and the first electrode P22 disposed in the second area A2 is transparent. And the bank P23 may be provided opaquely. For example, the first bank P13 disposed in the first area A1 may be a transparent bank, and the second bank P23 disposed in the second area A2 may be a black bank. However, the present invention is not limited thereto, and transparent banks may be disposed in both the first area A1 and the second area A2 . The black bank may be formed of a black material that absorbs light. However, since the black bank covers the edge of the first electrode P22 , a short circuit with the second electrode P25 may occur if the dielectric constant is high. Accordingly, the black bank may be formed of a black material having a low dielectric constant. The black bank cannot be disposed in the first area A1 because it reduces the transmittance of the external light EL to the auxiliary member 4 .

Since both the second electrode P15 disposed in the first area A1 and the second electrode P25 disposed in the second area A2 must be provided transparently, the first area ( A1) and the second area A2 may be provided transparently.

Although only one pixel is illustrated in each of the first area A1 and the second area A2 in FIGS. 2A to 2C , a plurality of pixels may be disposed in each of the first area A1 and the second area A2. can

Referring back to FIG. 1 , the main body 3 is for supporting the display panel 2 . The main body 3 forms the overall appearance of the display device 1 according to an example of the present application, and may be formed in a rectangular parallelepiped shape with an empty interior, but is not necessarily limited thereto. The display panel 2 may be supported by the main body 3 by being coupled to the main body 3 . The display panel 2 may be coupled to the main body 3 through an adhesive member such as resin or double-sided tape.

The main body 3 may include a receiving groove (H, shown in FIG. 2A). The accommodating groove H is for accommodating a printed circuit board for driving the display panel 2 , a driving device such as a battery, and an auxiliary member 4 . The receiving groove (H) may be provided by the display panel (2) and the main body (3), but is not necessarily limited thereto. If the driving device and the auxiliary member (4) can be accommodated, the receiving groove (H) is provided only by the main body (3) could be The body 3 may be formed of a metal material for rigidity, but may also be formed of a plastic material for weight reduction.

The main body 3 is provided to surround the display panel 2 , thereby preventing the display panel 2 from being damaged from external impact. Accordingly, the main body 3 may be disposed at the outermost portion of the display device 1 according to an example of the present application, as shown in FIG. 1 .

The auxiliary member 4 is a device disposed inside the main body 3, for example, may be a camera, a proximity sensor, an illuminance sensor, a speaker, and the like. Since the display device 1 according to an example of the present application is implemented as a full screen display, the auxiliary member 4 is formed inside the main body 3 so that the auxiliary member 4 does not protrude to the outside. It can be arranged in the receiving groove (H). Hereinafter, a case in which the auxiliary member 4 is a camera will be described as an example.

Since the auxiliary member 4 is disposed inside the main body 3 or under the display panel 3 , the first area A1 may be provided transparently so that external light can be incident on the auxiliary member 4 . . The first area A1 may be formed to have the same size as the auxiliary member 4 , but is not limited thereto and has a larger size than the auxiliary member 4 so that external light can be well incident on the auxiliary member 4 . may be provided as On the other hand, when the first area A1 is provided to be smaller than the auxiliary member 4, the amount of external light incident on the auxiliary member 4 is reduced and the amount of external light sensed by the auxiliary member 4 is reduced, so that the camera image is not displayed. Blurry issues may occur. However, if the width W2 of the first area A1 is too wide than the width W1 of the auxiliary member 4 (shown in FIG. 3 ), the external light EL reflected by the auxiliary member 4 is light-absorbed. The width W2 of the first area A1 is the width W1 of the auxiliary member 4 because it is not absorbed by the part 5 but is reflected back by a metal material such as a wiring and is incident on the auxiliary member 4 . ) or the external light EL reflected by the auxiliary member 4 may be adjusted within a range that is absorbed by the light absorption unit 5 .

Meanwhile, the auxiliary member 4 may be disposed to be spaced apart from the substrate P11 disposed in the first area A1 by a predetermined distance in a direction toward the inside of the body 3 . This is because when the auxiliary member 4 is in contact with the lower surface of the substrate P11, the auxiliary member 4 or the substrate P11 may be damaged when an external shock occurs. Accordingly, the auxiliary member 4 may be disposed to be spaced apart from the substrate P11 by a predetermined distance downward as shown in FIG. 2A . The distance (G, shown in FIG. 4) at which the auxiliary member 4 and the substrate P11 are spaced apart is the radius of the camera lens, and the external light EL reflected on the surface or inside of the camera lens is absorbed by the light absorbing part 5 It can be calculated by the distance moved to and the thickness of the camera lens.

For example, as shown in FIG. 4 , using the radius R of the camera lens and the distance ML that the external light EL reflected on the surface or inside of the camera lens moves to the light absorption unit 5 , the camera Calculate the angle θ between the bottom surface of the lens and the reflected external light EL, and calculate the distance D from the angle θ to the bottom surface of the camera lens and the bottom surface of the light absorption layer 5, By subtracting the thickness T of the circuit element layer PCL, the thickness of the display panel 2, and the thickness T of the camera lens from the distance D, the distance between the auxiliary member 4 and the substrate P11 is separated. (G) can be calculated.

The display device 1 according to an example of the present application may further include a support member 7 and an insertion member 8 .

The support member 7 is for supporting the auxiliary member 4 . The support member 7 according to an example may be coupled to the lower surface of the auxiliary member 4 inside the main body 3 . The support member 7 may be coupled to the body 3 to support the auxiliary member 4 . The support member 7 may be made of a light material such as plastic for weight reduction, but is not limited thereto, and may be made of a metal material if it can support the auxiliary member 4 . The support member 7 is provided with a size larger than that of the auxiliary member 4, so that the display panel 2 disposed in the second area A2, the circuit element layer PCL disposed thereon, and the insulating layer ( IL), the first electrode P22 , the second bank P23 , the organic light emitting layer P24 , the second electrode P25 , the encapsulation layer P26 , and the cover glass 6 may be supported. An insertion member 8 may be disposed between the display panel 2 and the support member 7 disposed in the second area A2 .

The insertion member 8 is for securing a space for the auxiliary member 4 to be disposed. The insert 8 may be coupled to the body 3, but is not limited thereto. The insertion member 8 may be disposed between the display panel 2 and the support member 7 in the second area A2 . The insertion member 8 may be disposed only in the second area A2 in order to prevent the absorption rate of external light EL with respect to the auxiliary member 4 from being lowered.

The insertion member 8 according to an example is provided to be thicker than the thickness of the auxiliary member 4, so that the auxiliary member 4 disposed in the first area A1 is disposed in the first area A1. 2) can be spaced apart a predetermined distance from. If the auxiliary member 4 is placed in contact with or too close to the lower surface of the display panel 2 disposed in the first area A1, the auxiliary member 4 and the first area A1 are disposed in the first area A1 even with a small external impact. This is because the display panel 2 collides and at least one of the auxiliary member 4 and the display panel 2 disposed in the first area A1 may be damaged. Therefore, the insertion member 8 is thicker than the auxiliary member 4 so that the auxiliary member 4 and the display panel 2 disposed in the first area A1 are spaced apart from each other by a distance that does not collide even with an external impact. It may be provided with a thickness.

The insert member 8 may be made of a material such as plastic, resin, metallic material, and impact mitigating material. For example, when the insertion member 8 is made of resin, the coupling force between the display panel 2 and the support member 7 disposed in the second area A2 may be increased. As another example, when the insertion member 8 is provided with a shock absorbing material, the insertion member 8 can absorb external impact, so that the auxiliary member 4 and the display panel 2 disposed in the first area A1 ) can effectively prevent collisions. As another example, when the insertion member 8 is made of a metal material, the heat emitted from the display panel 2 is transferred to the support member 7 or the main body 3, so that the heat emitted from the display panel 2 is It may have a heat sink function that transmits to the outside. However, in this case, a light absorbing material (or a light absorbing structure) for preventing external light EL reflection may be provided on a side surface adjacent to the auxiliary member 4 .

Referring again to FIG. 2A , the light absorbing unit 5 is for absorbing light. The light absorbing unit 5 according to an example is for absorbing external light EL reflected from the surface and the inside of the auxiliary member 4 such as a camera. The light absorbing part 5 may be made of a material that absorbs light to absorb external light EL reflected by the auxiliary member 4 . For example, the light absorbing part 5 may be made of a black material, and any black material may be used as long as it is a black resin, but the black material having a high dielectric constant is the first electrode P12 and the second electrode P15. ) may cause an electrical short. Accordingly, the light absorbing part 5 may be provided with one of black resin, graphite powder, gravure ink, black spray, and black enamel, which are photosensitive organic insulating materials with low dielectric constant. As another example, the light absorbing part 5 may be provided to include a light absorbing material such as carbon.

The light absorbing part 5 may be entirely made of black resin as shown in FIG. 2A, but is not limited thereto and only needs to absorb the external light EL reflected by the auxiliary member 4, so that the first region ( Only the side surfaces of the light absorbing part 5 adjacent to A1) may be made of black resin.

The light absorbing part 5 may be disposed in the second area A2 . In the display device 1 according to an example of the present application, the first area A1 disposed to overlap the auxiliary member 4 is provided transparently, thereby reducing the amount of external light EL incident on the auxiliary member 4 . By increasing it, the accuracy of the external light EL detected by the auxiliary member 4 may be improved. Accordingly, when the light absorption unit 5 overlaps the first area A1 , the light absorption unit 5 is disposed only in the second area A2 because it interferes with the external light EL incident on the auxiliary member 4 . can be

FIG. 5 is a schematic enlarged view of part Q of FIG. 1 , FIG. 6A is a schematic cross-sectional view of the line II-II shown in FIG. 5, and FIG. 6B is a schematic cross-sectional view of the line III-III shown in FIG. , FIG. 6C is a schematic cross-sectional view taken along line IV-IV shown in FIG. 5 , and FIG. 7 is a schematic view showing a part of FIG. 6A .

5 illustrates a first area A1, a second area A2, and a light disposed in a second area A2 to surround the first area A1 in the display device 1 according to an example of the present application. It is a schematically enlarged view of a part of the absorption part 5 .

FIG. 6A is a schematic cross-sectional view of the line II-II shown in FIG. 5 , which is a case in which the light absorption unit 5 is disposed in a boundary region between the sub-pixel and the sub-pixel. That is, it is a case in which the light absorption unit 5 is disposed to overlap the bank. As shown in FIG. 6A , the entire light absorbing part 5 may be disposed to overlap the second bank P23 disposed in the second area A2 . As described above, when the light absorbing part 5 is disposed to overlap the first area A1 , it is possible to block the external light EL directed to the auxiliary member 4 , so that the light absorbing part 5 is located in the second region A1 . It can only be placed in (A2).

Referring to FIG. 7 , the width LAW of the light absorbing part 5 may be equal to or smaller than the width BW of the second bank P23 . When the width LAW of the light absorbing portion 5 is greater than the width BW of the second bank P23, the auxiliary member 4 is partially overlapped with the first area A1. ) may reduce the absorption rate of external light (EL). Accordingly, in the display device 1 according to an example of the present application, the width LAW of the light absorbing part 5 is equal to or smaller than the width BW of the second bank P23, so that the auxiliary member 4 ), the light absorbing unit 5 may well absorb the external light EL reflected by the auxiliary member 4 without reducing the absorption rate of the external light EL.

Meanwhile, as shown in FIG. 7 , a portion of the light absorbing part 5 may be inserted into the second bank P23 transparently provided in the second area A2 . This is so that the light absorbing part 5 covers the first area A1 as wide as possible. As the thickness of the light absorbing part 5 surrounding the first area A1 is increased, the area capable of absorbing the external light EL reflected by the auxiliary member 4 increases, so that the external light of the light absorbing part 5 is increased. (EL) absorption rate can be improved. In this case, the thickness LAT of the light absorbing part 5 may be thicker than the thickness ILT of the insulating layer IL. More specifically, the thickness LAT of the light absorbing part 5 is the thickness ILT of the insulating layer IL and the thickness LIT of the light absorbing part 5 inserted into the second bank P23. It may be the summed thickness. The thickness LIT of the light absorbing part 5 inserted into the second bank P23 may be equal to or smaller than the thickness BT of the second bank P23. When the thickness LIT of the light absorbing part 5 inserted into the second bank P23 is greater than the thickness BT of the second bank P23, the light absorbing part 5 and the second bank P23 Since a step is generated between the two electrodes, the second electrode P25 may be disconnected. Accordingly, in the display device 1 according to an example of the present application, the thickness LIT of the light absorbing part 5 inserted into the second bank P23 is the same as the thickness BT of the second bank P23 or By being smaller, the light absorbing part 5 may absorb the external light EL reflected by the auxiliary member 4 while preventing the disconnection of the second electrode P25 .

FIG. 6B is a schematic cross-sectional view taken along line III-III shown in FIG. 5 , which is a case in which the light absorbing part 5 is disposed at a contact portion where the first electrode P12 and the transistor P17 are in contact. Accordingly, as shown in FIG. 6B , the organic light emitting layers P14 and P24 are not disposed on the first electrodes P12 and P22 , and the first and second banks P13 and P23 are formed on the first electrodes P12 and P22 . ) may be provided to cover. Here, the first bank P13 and the second bank P23 may be connected to each other. The entire light absorbing part 5 may be disposed to overlap the second bank P23 disposed in the second area A2 . When the light absorption unit 5 is disposed to overlap the first area A1 , the light absorption unit 5 is disposed only in the second area A2 because the external light EL directed toward the auxiliary member 4 can be blocked. can be Also, as in FIG. 6A , a portion of the light absorbing part 5 covers the first area A1 as wide as possible to improve the absorption rate of external light EL reflected by the auxiliary member 4 in the second area A2. It may be inserted into the transparent bank P23 disposed in the . Accordingly, the thickness LAT of the light absorbing part 5 is the sum of the thickness ILT of the insulating layer IL and the thickness LIT of the light absorbing part 5 inserted into the second bank P23 . can be provided with In addition, the thickness LIT of the light absorbing part 5 inserted into the second bank P23 is equal to or equal to the thickness BT of the second bank P23 in order to prevent the second electrode P25 from being disconnected. A smaller one may be provided.

FIG. 6C is a schematic cross-sectional view taken along line IV-IV shown in FIG. 5 , in a case in which a portion of the light absorbing unit 5 is disposed to overlap the sub-pixel. Accordingly, as shown in FIG. 6C , a portion of the light absorbing part 5 may overlap the second bank P23 which is a transparent bank. However, even in this case, the light absorbing unit 5 may be disposed in the second area A2 so as not to interfere with the external light EL directed toward the auxiliary member 4 .

Referring back to FIG. 6C , the light absorbing part 5 may not be inserted into the second bank P23 because it is disposed under the first electrode P12 . This is because, after the circuit element layer PCL is patterned, the light absorbing part 5 is formed in the patterned portion, then the first electrode P12 is formed and the second bank P23 is formed. Accordingly, as shown in FIG. 6C , the light absorbing part 5 is disposed only on the insulating layer IL to absorb the external light EL reflected by the auxiliary member 4 . And, in this case, the thickness of the light absorbing part 5 may be the same as the thickness of the insulating layer IL. As described above, the width of the light absorbing part 5 may be equal to or smaller than the width of the second bank P23.

FIG. 8A is a schematic cross-sectional view illustrating another example of FIG. 6A , FIG. 8B is a schematic cross-sectional view illustrating another example of FIG. 6B , and FIG. 8C is a schematic cross-sectional view illustrating another example of FIG. 6C .

8A to 8C are the same as the display device of FIGS. 6A to 6C except that the second bank P23 disposed in the second area A2 is provided as a black bank. However, even in this case, the second bank P23 and the light absorbing part 5 may be disposed so as not to overlap the first area A1 in order to improve the external light EL absorption rate of the auxiliary member 4 . Accordingly, the same reference numerals are assigned to the same components, and only different components will be described below.

In the case of the display device according to FIGS. 6A to 6C , both the first bank P13 and the second bank P23 are provided as transparent banks, so that the first area A1 and the second area A2 are divided. Since the bank may not be formed, the manufacturing process may be simplified. In particular, as shown in FIG. 6B , the first bank P13 and the second bank P23 disposed in the contact portion where the first electrode P12 and the transistor P17 are in contact are formed simultaneously in this process. Therefore, the upper surface of the first bank P13 and the upper surface of the second bank P23 may be provided with the same height and flat without a step difference. Accordingly, the second electrodes P15 and P25 provided on the first bank P13 and the second bank P23 may also be provided to be flat.

In contrast, in the case of the display device according to FIGS. 8A to 8C , the second bank P23 disposed in the second area A2 may be provided as a black bank.

First, in the case of FIG. 8A , since the second bank P23 disposed above the light absorption unit 5 is provided as a black bank, the second bank P23 absorbs the external light EL of the auxiliary member 4 . It may be disposed so as not to overlap the first area A1 so as not to interfere with the first area A1. Meanwhile, the light absorbing part 5 may overlap the second bank P23 which is the black bank. In addition, the light absorbing part 5 of FIG. 8A may be provided so as not to be inserted into the second bank P23, unlike FIG. 5A . This is because, since the second bank P23 is provided as a black bank, an area for absorbing the external light EL reflected by the auxiliary member 4 is sufficiently large even if the light absorption unit 5 is not inserted into the black bank. However, in this case, if the light absorption unit 5 and the second bank P23 are spaced apart, the external light EL reflected by the auxiliary member 4 between the light absorption unit 5 and the second bank P23 is a metal material. Because it can be reflected back to the light absorbing unit 5 may be provided to be connected to the second bank (P23). In the second bank P23, the insulating layer IL is patterned, the light absorbing part 5 is formed in the patterned portion, then the first electrodes P12 and P22 are patterned for each sub-pixel, and the first By being formed to cover the edges of the electrodes P12 and P22 , they may be connected to the light absorption unit 5 . When the first electrodes P12 and P22 are patterned for each sub-pixel, the upper surface of the light absorbing unit 5 is exposed, so when the second bank P23 is formed, the entire upper surface of the light absorbing unit 5 and the second bank ( P23) can be connected.

Next, in the case of FIG. 8B , after the first electrodes P12 and P22 are patterned for each sub-pixel, a second bank P23 , which is a black bank, is formed in the second area A2 , and then in the first area A1 . Since the first bank P13, which is a transparent bank, is formed, the first bank P13 may be thicker than the second bank P23. Accordingly, as shown in FIG. 8B , in the vicinity where the first bank P13 and the second bank P23 are adjacent to each other, the upper surface of the first bank P13 and the upper surface of the second bank P23 have different heights. A step may be formed. Accordingly, a step may also be formed between the second electrodes P15 and P25 provided on the first bank P13 and the second bank P23 .

Next, in the case of FIG. 8C , a portion of the light absorption unit 5 may overlap the second bank P23 which is a black bank. In addition, the rest except for a portion of the light absorbing part 5 may overlap the sub-pixels disposed in the first area A1 . In this case, the first area A1 may be disposed adjacent to the light absorbing part 5 because the light absorbing part 5 is located further to the left than the second bank P23 with reference to FIG. 8C . have. Accordingly, in this case, the second bank P23 may be positioned to be spaced apart from the first area A1 by a predetermined distance. The second bank P23, which is the black bank, is formed to cover the edges of the first electrodes P12 and P22 after the light absorbing part 5 and the first electrodes P12 and P22 are sequentially formed. The bank P23 may be connected to the light absorption unit 5 . When the first electrodes P12 and P22 are patterned for each sub-pixel, a part of the upper surface of the light absorbing part 5 is exposed, so that when the second bank P23 is formed, a part of the upper surface of the light absorbing part 5 and the second bank (P23) can be connected. Also, in the case of FIG. 8C , since the second bank P23 as a black bank is disposed above the light absorption unit 5 , the light absorption unit 5 may not be inserted into the black bank. In FIG. 6C , only the light absorbing unit 5 absorbs the external light EL reflected by the auxiliary member 4 , but in FIG. 8C , the black bank and the light absorbing unit 5 absorb the external light reflected by the auxiliary member 4 . because it absorbs That is, in the case of FIG. 8C , it is because an area capable of absorbing the external light reflected by the auxiliary member 4 is larger than that of FIG. 6C .

As a result, in the display device 1 according to an example of the present application, the light absorbing part 5 is provided to surround the first area A1 of the display panel 2 , and thus external light reflected from the auxiliary member 4 . It is possible to prevent the image overlapping or noise from being generated by preventing the EL from being incident on the auxiliary member 4 by being reflected back on a metal material such as wiring.

In addition, the light absorbing part 5 is disposed in the second area A2 so as not to overlap the first area A1, so that the absorption rate of the external light EL of the auxiliary member 4 can be increased. It is possible to improve the accuracy of the auxiliary member (4) for the.

In the present specification, it has been described that the light absorbing part 5 is disposed on the upper surface of the circuit element layer PCL having a flat surface, but the present invention is not limited thereto and the light absorbing part 5 is damaged by the transistors P17 and P27. The circuit element layer PCL is concavely patterned within a range not to be formed so that a part of the light absorption unit 5 (or the lower portion of the light absorption unit 5) is disposed up to the inside of the circuit element layer PCL. have.
